Answer:

x = 126

Step-by-step explanation:

-\frac{2}{7}x - \frac{8}{21}x + \frac{1}{3}x = -42

-\frac{2}{7}x (multiply numerator and denominator by 3)

-\frac{6}{21}x

\frac{1}{3}x (multiply numerator and denominator by 7)

\frac{7}{21}x

-\frac{6}{21}x - \frac{8}{21}x + \frac{7}{21}x = -42

-\frac{7}{21}x = -42 (multiply everything by -21)

7x = 882 (divide everything by 7)

x = 126

The equation V = 16300 (0.94)^t represents the value (in dollars) of a car t years after its purchase. Use this equation to comp
Dafna1 [17]

Solution:

Given:

V=16300(0.94)^t

The value of a car after t - years will depreciate.

Hence, the equation given represents the value after depreciation over t-years.

To get the rate, we compare the equation with the depreciation formula.

\begin{gathered} A=P(1-r)^t \\ \text{where;} \\ P\text{ is the original value} \\ r\text{ is the rate} \\ t\text{ is the time } \end{gathered}

Hence,

\begin{gathered} V=16300(0.94)^t \\ A=P(1-r)^t \\  \\ \text{Comparing both equations,} \\ P=16300 \\ 1-r=0.94 \\ 1-0.94=r \\ r=0.06 \\ To\text{ percentage,} \\ r=0.06\times100=6\text{ \%} \\  \\ \text{Hence, } \\ P\text{ is the purchase price} \\ r\text{ is the rate} \end{gathered}

Therefore, the value of this car is decreasing at a rate of 6%. The purchase price of the car was $16,300.

Subtracting with zeroes

The number would stay the same because, for example, 6 - 0 can't be 0 so it would be 6.

A what is an equation stating that two ratios or rates are equal
frozen [14]
The equation is
(A ≠ B)
A is the first number, ratio, rate, etc. , and B is the second.
The ≠ symbol means "does not equal", so the equation means:
[ Ratio A  is NOT equal to  Ratio B. ]
